IMPROVEMENT IN MACHINES FOR MAKING HoRsIsHoI-:sxr

Spccilication forming part of Lv'cttcrsvlatcnt No. 3,261, dated September 14, 1843.

.To allwhom it may concern:

Be` it known that I, HENRY BUEDEN, of the city of Troy, in the county of Rensselaer and State of vNew York, have -m'ade certain Improvements in the Machine for liflanufacturing Horseshoes, (for which machine I originally obtained Let-ters Patent ofthe United States,

under date of the 23d day of N ovember, 1835;)

Y and I do hereby declare that the following is a full and exact description of my said improvenients thereon. y

Ind the machine as originally patented byme the rod or bar of iron from which a 'shoe was to be made was 'cutoff above the grippingdies'or side-steels between which it was to be gri ppedland held while it was rolled and fashioned by the segment-swages, and after being cut oft it was allowed to fall between them.`

In my improved machine the rod or bar is passed directly in between the gripping-dies, and is cut ohc by a cutter on a level with and at the outer end of said dies. It. was found 'impracticabla also,in the machine as originally constructed to draw out and 'distribute the metal by the action of the segment-dies used in that machine by to give the metal the proportionate thickness an'dwidth requisite in its-different parts. In my improved machine this diiculty is obviated by giving to the swages a somewhat greater extent of motion than is given in the same time to the sliding frame, by which means they exert ya rubbing ordrawing power Lon the metal, drawing it from `the cutting end diminishing the time required for their per-l vformancej,I preventing the loss of heat, and insuring greater' accuracy in the work.

. Inthe accompanying drawings Figurel is aperspective view of thewhole machine. Fig. 2 is 'a side elevation, and Fig. 3 a top View or plan thereof. I Y

A A is the main frame, and-B B, a sliding rame,which is made .to traverse back and' so as e'i'ectually` to fill the Vspace between the gripping-pieces, and thereforth upon the main frame hy theaction of the crank' C. This and the general construction of my machiiieiare similar to that first pat ented by me; but'the` sliding frame is longer and moves'to a considerably greater distance. D D is the rack, which is bolted into the sliding frame, and into thisk rack the wheels E Finesh, as they do` likewise i-nto the lower wheels, ,G and H, the wheels 'E and F-being wide enonghon the face to engage both withl the rackand thelower wheels. I is the stationary and J, the movablegripping-die, which are shown separately in Fig. 4,- the movable die being represented as open.

Kis the cutter .on the movabledie J, which,"-`

die I, cuts ofi" the iron rod.

` u'In the position ofthe Inachineshown in Figs. I 1,2, and 3 the cut-01T piece is being acted uponA by the rolling and drawing segment-dies L1, andI M, and after passing these it is to be acted 'en by the grooving and punching dies N, the i piece being sustainedV by the lower segmentdie, O. When the piece has thus passed these segment-dies the gripping-dies will open, and I the iron will be then preparcd'for the bend` ing-machine, which is the same with that formerly used by'ine and fully described-in the` specification of the above-named Letters Iatcnt. rlhe opening and closing of the dies are effected in substantialiy` the same manner as in my original n1achine.

- To give to the segment-.dies L andk M the requisite drawing action I, in general, Aarrange the shafts of the wheels G and H so that they.f shall not be parallel to each other, as shownr.

in the segment, Fig. 5. 'In doing this the in-fi ner ends, I P, of the shafts which carry the segment-dies L and M, are to be ata greater distance from each other than -their opposite ends, IVI. Thedist-anceof the peripheries of the segment-dies from: their centers is to be proportionately increased, and the desired end. will ,be-,thereby accomplished, as the peripheries of the segment-'dies thus constructed will be made to travel'fsomewhat faster than the sliding frame. A like end vmay be attained by placing the shafts of the segment-dies parallel to each other; and so'gearing the wheels and rack'as that the segment-dies shall inlove' faster than the'carriage; but the former method is the most simple and is perfectly effective.

l .A `Having thus fully described the natbre of vdies for drawing out and distributing the met` with the latter, thereby allowing the bar of herein described and represented.

al with those for grooving-and punching it, so .1that.the,pieeeof metal'shallle carrieddirectly from the formertothe'latter'by av continued t movement of the sliding frame.

And Afor a full description ofl those parts or the said machine which it has not been thought necessary topresent) in the-present specification I hereby refer to the origi nal patent above named.

Iuyimprovements in the machine for mannfacturing horseshosgwhat I claim as new therein. and desire to secure by Letters Patent, is'- 1. The manner of combining and arranging thecutters'and gripping-dies in the said machine so that theformer be in the same plane iron to be passed directly in between them,l as

l 2. The causingof the peripheries'ofthe segment-dies L and M to travel faster than the sliding frame and the gripping-dies, for the Witnesses:- purpose andin the manner-abovemade known. Tno's. R JONES,

' 3. The manner of combining the segment EDWIN LIBRUNDAGE.
